Description
Technical field
The utility model relates to a kind of console switch, particularly relates to a kind of emergency power off switch.
Background technology
Because the voltage of electric motor car or hybrid vehicle is up to 300～400 volts, must be higher than the regular fuel car to the requirement of fail safe.As the electric motor car of sports products, in case of emergency, only depend on key to pass through the break-make that governor circuit is controlled electrical source of power indirectly, obviously be not enough, in case control system breaks down, be difficult to then guarantee that the safety of electrical source of power disconnects.
At present, have only the minority electric motor car to possess the unit switch of realizing the electrical source of power break-make by self plug, this type of unit switch has handle, latch and socket, and handle links to each other with latch, realizes the break-make of circuit by the plug of latch and socket.But the latch of this type of unit switch needs to aim at when inserting socket, comparatively requires great effort when extracting.
Summary of the invention
The purpose of this utility model is to overcome existing electric motor car safety combined switch and is not easy to realize outage that the inaccurate shortcoming of contraposition provides a kind of easy realization outage, the accurate emergency power off switch of contraposition.
A kind of emergency power off switch that the utility model provides, this switch comprises handle, socket and latch, latch can slide in described socket, wherein, described switch also comprises positioning disk and connecting rod, has track on the described positioning disk, have the primary importance and the second place on the described track, one end and the latch of described connecting rod are hinged, the other end and handle are hinged, described handle can slide between the primary importance in the described track and the second place, and when primary importance, described latch is arranged in the bonding station of socket; When the second place, described latch is arranged in the open position of socket.
When the emergency power off switch that adopts the utility model to provide cuts off the power supply to circuit, when handle in orbit primary importance and the second place between when mobile, the drivening rod action, the pulling latch, owing to vertical power is converted into the power of level, arm of force lengthening, and handle operates easily, therefore can be easy to the disconnection that realizes that latch is electrically connected with socket.Because latch slides in socket, socket plays guide effect to latch, when realizing that latch is electrically connected with socket, does not need socket is aimed at latch, and therefore, contraposition is more accurate.The emergency power off switch application that the utility model is provided can make the driver break down etc. in emergency circumstances at governor circuit when electric automobile, in time controls the shutoff of locomotive electrical source of power, guarantees vehicle safety.
